A Study of Physical Modeling and Mathematical Modeling on Inclusion Behavior in a Planar Flow Casting Process

Abstract

Flow pattern and inclusion removal in a novel-designed crucible in the planar flow casting process were studied in the present paper. A color dye water experiment was used to show the flow field and validate the mathematical modeling. It was shown that the flow pattern predicted by the Large Eddy Simulation model is maximally consistent with that in the physical modeling. The validated mathematical model was used to predict the flow pattern and inclusion behavior in the crucible with various prototypes using combinations of multiple facilities. The results show that the flow field, by using the stopper, enhances compared to that using none of the facilities, which causes the inclusion removal to become even worse when the stopper is individually used. Furthermore, as the magnetic field is added, the electromagnetic brake weakens the flow field in the magnetic zone. The function of the electromagnetic brake to weaken the flow pattern is most efficient for inclusion removal.

Numerical Modeling of Metallurgical Processes: Continuous Casting and Electroslag Remelting

“…Li et al [6] presented a two-phase LES model to simulate the thermal-magnetic-flow fields in a jumbo bloom caster with a mold electromagnetic stirring (MEMS), and the biased flow was identified and characterized. Liu et al [7] carried out an LES model to study the inclusion behavior in a planar flow casting process. Results show that the function of EMBr to weaken the flow pattern is most efficient for inclusion removal.…”
